We've been replacing incandescent and CFL lights as they fail. We found
that CFLs don't like being turned off/on a lot; it seems to increase
their failure rate. We've been doing this for about 4 years, and so far,
we have had zero LED failures. We like the LEDs because the color is
more natural than any of the CFLs. I don't know how many LED lights we
have, but well over half of our total lights are LED now.
Last year we replaced the recessed fluorescent lights (4 X 40W = 160W
total) in our kitchen with 9 "Halo" LED lights (9 X 8W = 72W total).
The LEDs produce far more light, and they are dimmable. In the evening
when we're not working in the kitchen, the lights are turned down to
maybe 25% of normal. In terms of energy usage we have to be less than
25% of what we used before, and the quality of the light is just many,
many times better.

I've converted some things to A type LED Bulbs at my house, mainly for
the reduced heat output, but I'm not seeing anywhere near the lifespan
advertised. I would say ~50% failure rate within 2 years. I'm betting
the actual LED's are fine, but the driver burns out. Is this common
with LED's or am I just really unlucky? We installed a bunch of 4'
LED Shop lights, granted they were all the same manufacturer, but we
have about 75% failed within 8 months.
